OK - I know this isn't in the Xtreme Makeover area, but here's my go at low key. The photo you have, sergio, is gorgeous and the low key is totally unnecessary. This was extremely difficult and my attempt is feeble.

Mactek, I agree with monkey143, unfortunatly the negative origin is still noticeable ( mostly because of the innatural white in the leaves and rocks ), however thatnx for posting .... it's an intersting possibility to keep in mind.
